Invasive Infection caused by Streptococcus pneumoniae serotype 19A

What is Invasive Infection caused by Streptococcus pneumoniae serotype 19A?

Invasive infection caused by Streptococcus pneumoniae serotype 19A is an infection of the bloodstream and other organs caused by Streptococcus pneumoniae that produces pneumococcal polysaccharide 19A antigen. This serotype has emerged in many countries and is associated with severe disease.

Symptoms of Invasive Infection caused by Streptococcus pneumoniae serotype 19A

The symptoms of invasive infection caused by Streptococcus pneumoniae serotype 19A vary depending on the part of the body that is infected. Common symptoms can include:

• Sore throat, cough, and chest pain
• Fever, chills, and sweating
• Headache, body aches, confusion, or other changes in mental status
• Nausea, vomiting, abdominal pain, and diarrhea
• Pain or tenderness in an area of the body, such as joints, abdomen, or chest

In infants and elderly people, symptoms may be subtle and difficult to identify, and can include vomiting, poor feeding, or difficult or rapid breathing.

Diagnosis of Invasive Infection caused by Streptococcus pneumoniae serotype 19A

Invasive infection caused by Streptococcus pneumoniae serotype 19A is usually diagnosed by laboratory testing of a sample from the body, such as blood or spinal fluid. This may include a culture that identifies the organism and determines its sensitivity to antibiotics.

Typically, the doctor will order imaging tests in order to identify any areas of infection in the body. These may include x-rays, CT scans, and other tests.

Treatment of Invasive Infection caused by Streptococcus pneumoniae serotype 19A

Due to the potentially severe nature of infections caused by S. pneumoniae serotype 19A, treatment is often started even before the results of laboratory tests are known. Treatment may include antibiotics, fluids, and other treatments, depending on the severity of the infection and the organs affected.

In some cases, surgery may be necessary to remove infected tissue or to drain an abscess. If an abscess forms, it may need to be aspired (sucked), drained, or surgically opened and cleaned.
